CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 394,362, dated December 11, 1888.

Application filed September 10, 1888. Serial No. 285,011. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANKLIN IIOCKEN- SMITH, of Irwin, in the county of \Vestmoreland and State of Pennsyl vania, have invented certain new and useful Improvements in Axle- Lubricators for RailroadCars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawing, which forms part of this SPGClfiC-flljlOll.

My invention relates to an improvement in axle-lubricators for railroad-cars; and it consists in the combination,with a wheel, of two oil-chambers placed upon opposite sides thereof, each chamber being provided with an internal flange or bracket, as will be more fully described hereinafter.

The object of my invention is to place inside of each of the chambers a flange, bracket, or partition which extends past the fillinghole for the purpose of enabling a larger quantity of oil to be placed in each chamber without running out, and to prevent the oil from spilling through the filling-hole, especially when the wheel is rum'iing upon a curve.

The accompanying drawing represents a vertical section of a wheel to which my invention is applied.

A represents the wheel, and B its hub, which is provided with a lubricating-groove, C, which makes connection with each one of the lubricating-chambers I), as shown. I do not limit myself to the particular form of groove shown, for this may be varied at will; but the groove should make connection with each of the chambers, so that any oil which runs from one chamber, owing to the position in which the wheel is, will pass into the other one, and thus prevent it from leaking through the hub.

The oil-chambers D may be made of any desired shape, and each one is provided with a filling-hole, G, upon its outer side, through which the lubricatingmaterial is poured. Inside of each chamber is a flange, partition, or bracket, I, which extends from the outer side of the chamber a suitable distance past the filling-ope11ing,but which does not extend all the way to the hub, as shown.

The lubricator on being poured through the filling-hole first passes through the outer and smaller chamber, 0, from which it can freely pass as the wheel revolves into the larger chamber. As the wheel revolves, the oil evenly fills both compartments of the chambers D, and these partitions serve to prevent the oil from being thrown by centrifugal force through the filling-openings while the wheels are running upon a curve, and also to enable a larger quantity of oil to be poured into the chambers 1) than can be done where no partitions are used. The partitions I prevent the oil from having an endwise movement, which would cause the oil to be thrown out of the openings G. If the partitions are not used, there is nothing to prevent the oil from being dashed directly through the opening G, and therefore the partitions, by preventing this waste of the oil, enables a larger quantity to be poured into the chambers than can be done without them. These partitions serve as guards for the filling-holes and prevent any waste of oil therefrom. are used, but comparatively a small amount of oil can be poured into the chambers before it will begin to waste through the filling-holes, and thus the wheels require to be lubricated frequently. Brackets, flanges, or partitions prevent the oil from running out, because the brackets extend beyond the filling-openings, and a greater quantity is held in the large compartments of the lubricating-chambers D.

Having thus described my invention, I

- claim inner ends past the filling-holes, substantially 0 as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANKLIN C. HOCKENSMITII.
